Functions of OSI and TCP/IP Layers Q.5

0. A router has two full-duplex Ethernet interfaces each operating at 100 Mb/s. Ethernet frames are at least 84 bytes long (including the Preamble and the Inter-Packet-Gap).
The maximum packet processing time at the router for wirespeed forwarding to be possible is (in micro-seconds)

  • Option : B
  • Explanation : Minimum transmission time
    = (84 bytes) / (2*100 bps)
    = (84 * 8 bits) / (2*100 bps)
    = 3.36 seconds
